24FC256-I/ST Frequently Asked Questions (FAQ)

  • The maximum clock frequency for the 24FC256-I/ST is 1 MHz.

  • To ensure data integrity, use the Page Write operation with a valid address and data, and verify the write cycle status using the Status Register.

  • The WP (Write Protect) pin is used to prevent accidental writes to the device. When WP is low, the device is in a write-protected state, and any write attempts will be ignored.

  • No, the 24FC256-I/ST is a 2.5V device and should not be used in a 5V system. Operating the device at 5V can cause damage or malfunction.

  • During power-up, the device should be held in a reset state until the power supply has stabilized. During power-down, the device should be placed in a standby mode to minimize power consumption.
